Protection Relay:Types, wiring diagram and working principle.
Protection relay is an electromechanical monitoring safety device which senses fault and provide trip signal to the breaker as per set value in LT and HT panel.
Home / What is a relay protection board
Protection relay panels are panels that protect the electrical installation against possible problems. It works like an electronic switch designed to cut the electric current in case of a possible failure by measuring various parameters with the relays included in the protection relay. At its core, a Relay Board consists of one or more relays—electrically controlled switches that control high-voltage devices using low-voltage signals. Simply put, it's like a magic switch: with a tiny signal, you can turn on a light bulb or start a water pump. These panels prevent the installation from being damaged by interrupting the circuits, especially in unexpected situations such as overcurrent or high voltage. With extensive experience and a rigorous quality control program, nVent collaborates closely with your team to engineer high-quality relay panels.
